[Chris] says that he’s been pretty busy lately, leaving little opportunity for hacking. However he did manage to find a little time to put together a small project that has occupied his to-do list for a while – a floppy drive music controller.
We have seen hacks that use microcontrollers to actuate floppy drive motors before, but we can’t remember anything that used a calculator to do the job instead. While a microcontroller gives you plenty of I/O pins to play with, [Chris’] Ti-83+ only has two.
Even with the calculator’s I/O limitations, he didn’t find the task too overly difficult as he merely needed to hold a pair of the drive’s pins low, while pulsing two others. He modified a media player written for Ti calculators to output the necessary control signals, then he cranked out some tunes.
As you can see in the video below, his simple setup works quite well – not bad for just a few hours’ work.
